So the fact that some projects are using some new server driven technology for some features doesn’t really prove anything.
Unless they specifically announce they are dropping RN support from the app or you see a big drop off in pull request activity I wouldn’t jump to any conclusions.
>The path of a world that is 100% native or 100% React Native is relatively straightforward.
but ultimately... hybrid apps are hard. Airbnb had a ton of infrastructure that needed porting over to RN that often required contributing upstream to fix issues they found. If you're starting from scratch you can get pretty far sticking to React/JS.
imo I can't imagine a startup using anything other than RN (or react-native-web) because of how quickly you can build things.
Server-driven UI rendering and Litho/ComponentKit are also growing along with React Native. Facebook app has a big enough surface that it makes sense to have different rendering strategies for different use cases.
That's an odd statement. Playing mix-n-match with rendering strategies without a very clear UX justification for doing it is an invitation for designers and mediocre product people to indulge themselves at the expense of the overall UX.
